Inclusive language and gender perspective in advertising
En el diseño de estrategias creativas que ayude a las compañías a erigirse como marcas útiles o con propósito, uno de los aspectos clave hoy en día es el relacionado con la igualdad de género, expresada tanto a través de la presencia en las historias publicitarias de situaciones igualitarias que rompan con estereotipos de género como mediante el uso de fórmulas de lenguaje inclusivo. El principal objetivo del estudio es analizar los elementos de lenguaje inclusivo y de perspectiva de género presentes en las campañas publicitarias, a partir de una muestra de 66 acciones premiadas en la edición de 2022 de El Sol, Festival Iberoamericano de la Comunicación Publicitaria. Los resultados evidencian que las acciones en las que se tiene en cuenta el lenguaje inclusivo son minoritarias, que entre las campañas premiadas existen acciones con presencia de situaciones de tipo patriarcal, con exposición de cuerpos normativos y con cosificación de la mujer y que son los anunciantes los que publican, con más frecuencia que las agencias, compromisos en este sentido, especialmente en sus programas de Responsabilidad Social Corporativa. Si bien las empresas están asumiendo un papel más activo incorporando en sus políticas cuestiones de inclusión y diversidad, es importante el diseño de un discurso responsable, especialmente en las estrategias de comunicación persuasiva, que fomente la igualdad y en el que se emplee un lenguaje inclusivo.In the design of creative strategies that help companies to establish themselves as useful or purposeful brands, one of the key aspects today is related to gender equality, expressed both through the presence in advertising stories of egalitarian situations that break with gender stereotypes and through the use of inclusive language formulas. The main objective of the study is to analyze the elements of inclusive language and gender perspective present in advertising campaigns, based on a sample of 66 actions awarded in the 2022 edition of El Sol, Ibero-American Festival of Advertising Communication. The results show that the actions in which inclusive language is taken into account are a minority, that among the winning campaigns there are actions with presence of patriarchal situations, with exposure of normative bodies and with objectification of women and that it is advertisers who publish, more frequently than agencies, commitments in this regard, especially in its Corporate Social Responsibility programs. While companies are taking a more active role by incorporating inclusion and diversity issues into their policies, it is important to design a responsible discourse, especially in persuasive communication strategies, that promotes equality and in which inclusive language is used
Resensitization in suspected penicillin allergy
Background
The diagnosis of allergic reactions to penicillins (AR-PEN) is very complex as there is a loss of sensitization over time, which leads to negative skin tests (STs) and specific IgE in serum, and even to tolerance to the drug involved. However, STs may become positive after subsequent exposure to the culprit drug (resensitization), with the risk of inducing potentially severe reactions. The exact rate of resensitization to penicillins is unknown, ranging from 0% to 27.9% in published studies.
Objectives
To analyze the rate of resensitization in patients with suggestive AR-PEN by repeating STs (retest) after an initial evaluation (IE).
Material and Methods
Patients with suspected AR-PEN were prospectively evaluated between 2017 and 2020. They underwent STs, and a randomized group also underwent a drug provocation test (DPT) with the culprit. Only patients with negative STs and/or DPT were included. All included cases were retested by STs at 2–8 weeks.
Results
A total of 545 patients were included: 296 reporting immediate reactions (IRs) and 249 non-immediate reactions (NIRs). Eighty (14.7%) cases had positive results in retest (RT+): 63 (21.3%) IRs and 17 (6.8%) NIRs (p < 0.0001). The rate of RT+ was higher in anaphylaxis compared with all other reactions (45.8% vs 9.1%, p < 0.0001). The risk of RT+ was higher from the fifth week after IE (OR: 4.64, CI: 2.1–11.6; p < 0.001) and increased with the patient's age (OR: 1.02; CI: 1.01–1.04; p = 0.009).
Conclusions
Due to the high rate of resensitization, retest should be included in the diagnostic algorithm of IRs to penicillins after an initial negative study, especially in anaphylaxis, to avoid potentially severe reactions after subsequent prescriptions of these drugs.he present study has been supported by Institute of Health “Carlos III” of the Ministry of Economy and Competitiveness (grants cofunded by European Regional Development Fund (ERDF): PI18/00095, RETIC ARADYAL RD16/0006/0001).

Diagnosis of immediate reactions to amoxicillin: Comparison of basophil activation markers CD63 and CD203c in a prospective study
Amoxicillin (AX) combined or not with clavulanic acid (CLV) is frequently involved in IgE-mediated reactions. Drug provocation test (DPT) is considered as the gold standard for diagnosis, although contraindicated in high-risk patients. Basophil activation test (BAT) can help diagnose immediate reactions to beta-lactams, although controversy exists regarding the best activation marker. We have performed a real-life study in a prospective cohort to analyze the real value of BAT as diagnostic tool and the best activation marker, CD63 and CD203c, for the evaluation of immediate reactions to these drugs.We thank Claudia Corazza for her invaluable English language support; Verónica Prados and Ana Molina for their help in technical support in flow cytometry methods.

Detection of Serum-Specific IgE by Fluoro-Enzyme Immunoassay for Diagnosing Type I Hypersensitivity Reactions to Penicillins
Diagnosis of type I hypersensitivity reactions (IgE-mediated reactions) to penicillins is based on clinical history, skin tests (STs), and drug provocation tests (DPTs). Among in vitro complementary tests, the fluoro-enzyme immunoassay (FEIA) ImmunoCAP® (Thermo-Fisher, Waltham, MA, USA) is the most widely used commercial method for detecting drug-specific IgE (sIgE). In this study, we aimed to analyze the utility of ImmunoCAP® for detecting sIgE to penicillin G (PG) and amoxicillin (AX) in patients with confirmed penicillin allergy. The study includes 139 and 250 patients evaluated in Spain and Italy, respectively. All had experienced type I hypersensitivity reactions to penicillins confirmed by positive STs. Additionally, selective or cross-reactive reactions were confirmed by DPTs in a subgroup of patients for further analysis. Positive ImmunoCAP® results were 39.6% for PG and/or AX in Spanish subjects and 52.4% in Italian subjects. When only PG or AX sIgE where analyzed, the percentages were 15.1% and 30.4%, respectively, in Spanish patients; and 38.9% and 46% in Italian ones. The analysis of positive STs showed a statistically significant higher percentage of positive STs to PG determinants in Italian patients. False-positive results to PG (16%) were detected in selective AX patients with confirmed PG tolerance. Low and variable sensitivity values observed in a well-defined population with confirmed allergy diagnosis, as well as false-positive results to PG, suggest that ImmunoCAP® is a diagnostic tool with relevant limitations in the evaluation of subjects with type I hypersensitivity reactions to penicillinsThis research was funded by the Institute of Health ‘Carlos III’ (ISCIII) of the Ministry of Economy and Competitiveness (MINECO) (grants cofunded by European Regional Development Fund: PI15/01206, PI17/01237, PI18/00095, RETICS ARADYAL RD16/0006/0001).

Synthetic antigenic determinants of clavulanic acid induce dendritic cell maturation and specific T cell proliferation in patients with immediate hypersensitivity reactions
Background
Immediate drug hypersensitivity reactions (IDHRs) to clavulanic acid (CLV) have increased in the last decades due to a higher consumption alongside amoxicillin (AX). Due to its chemical instability, diagnostic procedures to evaluate IDHRs to CLV are difficult, and current in vitro assays do not have an optimal sensitivity. The inclusion of the specific metabolites after CLV degradation, which are efficiently recognised by the immune system, could help to improve sensitivity of in vitro tests.
Methods
Recognition by dendritic cells (DCs) of CLV and the synthetic analogues of two of its hypothesised antigenic determinants (ADs) was evaluated by flow cytometry in 27 allergic patients (AP) and healthy controls (HC). Their ability to trigger the proliferation of T cells was also analysed by flow cytometry.
Results
The inclusion of synthetic analogues of CLV ADs, significantly increased the expression of maturation markers on DCs from AP compared to HC. A different recognition pattern could be observed with each AD, and, therefore, the inclusion of both ADs achieves an improved sensitivity. The addition of synthetic ADs analogues increased the proliferative response of CD4+Th2 compared to the addition of native CLV. The combination of results from both ADs increased the sensitivity of proliferative assays from 19% to 65% with a specificity higher than 90%.
Conclusions
Synthetic ADs from CLV are efficiently recognised by DCs with ability to activate CD4+Th2 cells from AP. The combination of analogues from both ADs, significantly increased the sensitivity of DC maturation and T-cell proliferation compared to native CLV.This work has been supported by Institute of Health ‘Carlos III’ (ISCIII) of the Ministry of Economy and Competitiveness (MINECO) (grants co-funded by European Regional Development Fund: PI15/01206, PI17/01237, PI18/00095, PI20/01734, RETICS ARADYAL RD16/0006/0001); Andalusian Regional Ministry of Health (grants PI-0241-2016, PE-0172-2018, PI-0127-2020); Spanish Ministerio de Ciencia e Innovación (Proyectos de I+D+I «Programación Conjunta Internacional», EuroNanoMed 2019 (PCI2019-111825-2), Ministerio de Ciencia y Educación (PID2019-104293GB-I00), Instituto de Salud Carlos III (ISCIII) of MINECO (RD16/0006/0012), Junta de Andalucía ( PY20_00384 ).

Differential presentation of hypersensitivity reactions to carboplatin and oxaliplatin: Phenotypes, endotypes, and management with desensitization
Background: Drug hypersensitivity reactions (DHRs) to platinum-based drugs are
heterogenous and restrict their access, and drug desensitization (DD) has provided a
ground-breaking procedure for their re-introduction, although the response is heterogeneous. We aimed to identify the phenotypes, endotypes, and biomarkers of reactions
to carboplatin and oxaliplatin and their response to DD. Methods: Seventy-nine patients presenting with DHRs to oxaliplatin (N = 46) and carboplatin (N = 33) were evaluated at the Allergy Departments of two tertiary care hospitals in Spain. Patient symptoms, skin testing, biomarkers, and outcomes of 267 DDs were retrospectively analyzed.
Results: Oxaliplatin-reactive patients presented with type I (74%), cytokine release
reaction (CRR) (11%), and mixed (Mx) (15%) phenotypes. In contrast, carboplatin reactive patients presented with predominantly type I (85%) and Mx (15%) but no CRRs. Out of 267 DDs, breakthrough reactions (BTRs) to oxaliplatin occurred twice as frequently as carboplatin (32% vs. 15%; p < .05). Phenotype switching from type I to another phenotype was observed in 46% of oxaliplatin DDs compared to 21% of carboplatin DDs. Tryptase was elevated in type I and Mx reactions, and IL-6 in CRR and Mx, indicating different mechanisms and endotypes. Conclusion: Carboplatin and oxaliplatin induced three different types of reactions with defined phenotypes and endotypes amendable to DD. Although most of the initial reactions for both were type I, oxaliplatin presented with unique CRR reactions. During DD, carboplatin reactive patients presented mostly type I BTR, while oxaliplatin-reactive patients frequently switched from type I to CRR, providing a critical difference and the need for personalized DD protocols
ATM/ATR kinases link the synaptonemal complex and DNA double-strand break repair pathway choice
DNA double-strand breaks (DSBs) are deleterious lesions, which must be repaired precisely to maintain genomic stability. During meiosis, programmed DSBs are repaired via homologous recombination (HR) while repair using the nonhomologous end joining (NHEJ) pathway is inhibited, thereby ensuring crossover formation and accurate chromosome segregation.1,2 How DSB repair pathway choice is implemented during meiosis is unknown. In C. elegans, meiotic DSB repair takes place in the context of the fully formed, highly dynamic zipper-like structure present between homologous chromosomes called the synaptonemal complex (SC).3,4,5,6,7,8,9 The SC consists of a pair of lateral elements bridged by a central region composed of the SYP proteins in C. elegans. How the structural components of the SC are regulated to maintain the architectural integrity of the assembled SC around DSB repair sites remained unclear. Here, we show that SYP-4, a central region component of the SC, is phosphorylated at Serine 447 in a manner dependent on DSBs and the ATM/ATR DNA damage response kinases. We show that this SYP-4 phosphorylation is critical for preserving the SC structure following exogenous (γ-IR-induced) DSB formation and for promoting normal DSB repair progression and crossover patterning following SPO-11-dependent and exogenous DSBs. We propose a model in which ATM/ATR-dependent phosphorylation of SYP-4 at the S447 site plays important roles both in maintaining the architectural integrity of the SC following DSB formation and in warding off repair via the NHEJ repair pathway, thereby preventing aneuploidy.This work was supported by CIHR grant 119468 to M.Z., a MRC core-funded grant to E.M.-P., and National Institutes of Health grant R01GM072551 to M.P.C.Peer reviewe
